A torsion coil spring using coils in two locations! High-difficulty production is possible with our in-house developed equipment.
At RIKEN Hatsujou Industry, we are able to produce springs with a small spring index, which are difficult to manufacture by other companies, using our own developed equipment. The double torsion spring is a twisted coil spring that uses coils at two points. Since it can stand alone as a single spring, design becomes easier, and it is possible to eliminate the core pin. If both sides have the same shape, the load value can be determined by multiplying the load value on one side by two. For the "Twisted Coil Spring Design Software," please contact us via the inquiry form or email. We distribute it via email. *For more details, please refer to the PDF document or feel free to contact us.
